Abstract: PURPOSE:To increase the pitch of word lines without changing the selection system of a cell as compared with that in conventional cases by a method wherein a word line and a plate electrode which are owned jointly by two cells which are adjacent in a direction in which the bit line is run are formed so as to be deviated in a direction in which the bit line is run. CONSTITUTION:For example, memory cells Cn,n, Cn+1 which are connected to one bit line BL41 are laid out in such a way that they are connected to one word line WLn. On the other hand, plate electrodes PLn, PLn+1 are laid out in such a way that they are deviated by a half pitch with reference to the word line WLn, and the two cells Cn,n Cn,n+1 which are connected to one bit line WL and one bit line WL41, are connected to other electrodes. Thereby, the two memory cells are connected to every word line and every bit line, the plate electrode is made inactive in the cell from which data is to be read out, and, before the word lines are selected, the plate electrode is set to an active state in the cell from which data is not to be read out. Consequently, the pitch of the word lines ca be increased.

Title: Process for molecular beam epitaxial growth
Inventor: SUGAO SHIGEO
IPC: C30B23/08
Filed: 1988-12-06
Abstract: PURPOSE:To obtain a grown layer having suppressed carbon contamination by irradiating a substrate with atomic hydrogen during the crystal growth in a molecular beam epitaxial growth process using an organometallic compound as a molecular beam source. CONSTITUTION:A GaAs substrate 13 having a surface cleaned by chemical etching and degassing treatment is attached to a substrate holder 12 and the growth chamber 10 is evacuated in high vacuum with a vacuum pump 11. The heating of the substrate 13 is started and, when the substrate temperature exceeds 400 deg.C, AsH3 gas is introduced into an arsenic molecular beam source 14 to irradiate the substrate with As beam and prevent the deterioration of the substrate 13 caused by the elimination of arsenic. When the substrate temperature reaches the growth temperature, EG gas (triethylgallium gas) and H2 gas are introduced into a TEG molecular beam source 15 and an atomic hydrogen source 16, respectively to effect the growth of a crystal. Ethyl radical causing the carbon contamination can be converted into ethane having low reactivity by this process in high efficiency. The inclusion of carbon in the grown layer can be suppressed and a grown layer having extremely low carbon contamination (a p-type impurity concentration of <=10<14>cm<-3>) can be produced by this process.

Title: Automatic train controller
Inventor: SASAJIMA YOSHIO
IPC: B60L15/40
Filed: 1992-10-23
Abstract: PURPOSE:To eliminate a ground facility by sending a signal having an identification code of an own train in an advancing direction from a head of trains, detecting reflection from a preceding train, and braking it when an interval to the preceding train obtained from a time difference between a starting ground point and a receiving ground point is a predetermined value or less. CONSTITUTION:A transmitting antenna 2 and a reception antenna 5 are mounted at a head of an own train (a) advancing in a direction of an arrow on rails R. A transmitter 10 forms a signal having an identification code of the train (a), and transmits it from the antenna 2 toward a preceding train (b). A signal reflected on a reflecting plate 4 of a tail 3 of the train (b) is received by the antenna 5, and input to a operator 30 through a receiver 20. The operator 30 operates a distance to the train (b) from a transmitting time, a receiving time and a traveled distance therebetween. When the obtained distance is a predetermined value or more, it is traveled at a predetermined speed as it is, while when it is the predetermined value or less, it is braked/stopped. Thus, an unnecessary closing system in a ground facility is realized to reduce expenses, and an operating interval is shortened.

Title: Spread spectrum signal demodulator
Inventor: MATSUNO TATSUJI
IPC: H04J13/00
Filed: 1990-11-15
Abstract: PURPOSE:To demodulate a data accurately by using a timing signal generated through the detection of a maximum value of a signal resulting from addition of output signals of each correlation device so as to compare the output signals of each correlation device and resulting in outputting a state value so as to obtain an original information data. CONSTITUTION:Let bits to be sent be '11001...', then a PN series comprising PN0, PN0, PN1, PN1, PN0... is sent sequentially at a sender side, After the absolute value of outputs of each correlation device is obtained, both the outputs are added to obtain the sum. Since the signal is not distinct for each bit but there is a peak in the series, a maximum detection circuit P1 detects each peak and generates a comparison timing pulse for each peak. The pulse is inputted to a processing circuit CONT and an output of the comparator circuit COMP is discriminated to be a data bit in the timing when the pulse is given to execute data demodulation. Thus, even when a peak in excess of a prescribed threshold level is not in existence in the correlation output, the correlation values are compared based on a tentative peak position, then the data is accurately demodulated.

Abstract: PURPOSE:To control the internal temperature of a vacuum heat insulated vessel without requiring a large-scaled power source such as a blower or vacuum pump. CONSTITUTION:A vacuum heat insulating layer 6 is formed by vacuum exhausting the space between an inner wall 3 and an outer wall 4 in the close state. An adsorptive member 21 capable of releasing and adsorbing the residual gas by heating and cooling is provided on the outer wall 4 side in the inner part of the vacuum heat insulating layer 6. The high temperature air in the vessel is guided to the outer surface of the outer wall 4 in the part having the adsorptive member 21, and the adsorptive member 21 is heated from the outside of the vessel. Thus, the adsorbed residual gas is released, the degree of vacuum of the vacuum heat insulating layer 6 is lowered, the heat conductivity is increased to release the heat, and the temperature in the vessel is thus lowered.
